SPECIFICATION forming part of Letters Patent No. 385,050, dated June 26, 1888.

Application filed October 27, 1887. Serial No. 253,522. (No model.)

To all whom it may concern.'

Be it known that I, GABRIEL J oHAN WIL- HELM GALsTER, a subject of the King of Denmark, and a resident of New York city, in the county of New York and State of New York, haveinvented certain new and usefulImprovements in OlothOutting Machines, of which the following is a specification.

My present invention relates to an improved device for cutting forms or patterns from a layer or series of layers of fibrous or other material adapted to be made up into clothing or other silnilar articles in which sections of a given form or conguration are essential to the perfection of the garment or article when the sections are united.

The accompanying drawings form a part of this specification and illustrate the best mode of carrying my invention into effect.

In the accompanying drawings, Figure l is a side elevation of a device embodying my invention. Fig.' 2 is a vertical section on the lineX X, Fig. 1. Fig. 3 is a plan view. Fig. 4 is a section of the air-valve. Fig. 5 illustrates one of the, applications of my invention.

In the drawings, A is a bed-plate having a tapering forward portion', A', adapted to pass under the layer or layers of material to be cnt. To the upper side of this bed-plate is attached a vertical standard, B, adapted to support a rotary cutter, H, and the operativeparts of the apparatus by which the cutter fis driven.

O is an air-cylinder of any suitable construction, provided with rotary piston-wheels D D', from which a rotary motion is transmitted to the cutter H through the pinions E and G and the intermediate gear-wheel, F. The rotary pistons D D are journaled in the air-cylinder, so that the teeth of the same will iit and form a tight joint with the inner surface of the cylinder, which is described on the periphery of a circle in the ordinary manner.

The pinion E is placed on the axis of the piston-wheel D, which is extended through the casing of the cylinder C for that purpose, as shown in Fig. 2.

Theintermediate gear-wheel, F, meshes with the pinion E and with the pinion G, and is journaled on the outside ofthe air-cylinder C in any suitable manner.

The pinion G and the rotary cutter H are attached to the oppositev ends of a shaft, I, as

shown, the shaft I being journaled in a projection, J, from the cylinder C. The shaft I is extended through a slot, z', in the standard B, as shown, and the cutter H is attached to it on the outside of the standard. The sllot iis elongated vertically to permit of a vertical adj ustment of the cutting devices upon the standard, in a manner which will be presently described.

The piston-wheels D D are driven in the ordinary manner by compressed air or gas admitted into the aircylinder (l through the in let-pipe O and supply-pipe S. The escape opening is indicated at P. The admission of the air or gas to the cylinder may be controlled by a two-way valve, O, located at the junctionof the inlet-pipe O and the supplypipe S. The valve itself, as shown in the drawings, is controlled by a lever, Q, one movement of which opens a passage from the snpplypipe S through the valve to the inlet-pipe 0, and a movement of which in the opposite direction closes the passage from the supplypipe S and opens a passage from the inlet-pipe O to the air, so that the air or gas in the machine may escapeand the operation of the machine may be arrested.

The lever Q is provided with a convenient hand-hold, q, as shown, and the parts are so arranged that when the lever is lifted by the pressure of the finger against the action of the spring T the air passes in through inlet R. The air passes from pipe S through the inlet R in the valve, through pipe O, to the inachine.4 When the linger is taken from the lever, the spring T draws the lever Q back, and air passes out through the outlet U, thereby stoppingthemachineimmediately. Thehand hold q is arranged in convenient proximity to the handle V, so that the machine may be guided and controlled by one hand of the operator, leaving the other hand free for other purposes.

The supply-pipeS is made of rubber or other flexible material of suitable character, and is of any desired length, so that the machine may be moved about from table to table, as desired, as shown in Fig. 5.

The cylinder C, with the parts attached, is adj nstably secured to the standard B by means of the screw K, passing through a slot, K', in the upper part of the standard, as shown.

By loosening the screw K the entire ma IOO chine may be lifted or lowered, so as to take up the wear of the cutter or to adjust the machine to the requirements of the occasion.

The relation of the cylinder C to the standard B is maintained by means of the engagement of the shaft I with the sides of the slot t' in the standard, and it is further maintained by means of the projections or bosses d d' on the ends of the cylinder, which extend into slots 7a k in the standard B. These projections iit the slots la cand prevent the cylinder from tipping when it receives a vertical adjustment on the standard B. The projections are hollowed out, as shown, to form extended bearings for the shafts of the piston-wheels D D.

L represents an emery-wheci or other suitable sharpening device adjustably secured to the standard B in convenient proximity to the cutter H, so that it may be brought into and out of operative relation to the cutter. It is mounted upon one end of a lever, X, pivoted at M, the other end of'which is provided with f' a suitable hand-hold, N. Through lever X the Wheel'L may be brought to bear upon the cutting-edge ofY the wheel H, so that the eutter may be ground down and sharpened by the motion communicated to it by its driving mechanism. The hand-h old N is arranged in convenient proximity to the handle W, as described in connection with the hand-hold g.

W represents a handle by which the machine can be presented to the work and be manipulated, as described.

The operation of the machineis as follows: The cutter is presented to the work and the compressed air or gas is admitted to the cylinder C by raising the lever Q against the action of the spring T. The piston-wheels D D are then driven in the direction of the arrows, as shown, the motion of the piston-wheel D giving rise to a corresponding'motion of the pinion E, which motion is transmitted through the intermediate gear-wheel, F, to the pinion G, thereby giving the desired rotary motion to the circular knife H. When it is desired to lessen the speed or stop the machine, either temporarily or permanently, the pressure on the ,lever Q is wholly or partially relieved, thus wholly or partially shutting oft the snpply. It will be obvious thatV the construction now described results in a small-sized compact machine, complete in itself, and which may be readily moved from table to table, as desired. In this wayI am enabled to dispense with the devices ordinarily employed for communicating motion from a stationary source of power to a movable cutter.

I do not in this application claim, broadly, a rotary cutter or an air or gas motor, as I am aware that these devices are well known; but

1. In a cloth-cutting machine, the combination, with a bed-plate and a vertical standard rigidly connected together, of a rotary air or gas motor secured to the latter, a flexible supply-pipe, and a rotary knife driven by said motor and supported by said standard, as and for the purpose described.

2. In a cloth-cutting machine, the combination, with a bed-plate and a vertical standard rigidly connected together, of a rotary air or gas motor secured to the latter and provided with a handle, a exible supply-pipe, arotary knife driven by said motor and supported on said standard, and a supply-cock having a hand-hold in convenient proximity to said handle, as and for the purpose described.

3. In a cloth-cutting machine, the combination, with a bed-plate and a vertical standard, of a rotary air or. gas mot-or secured to the latter, a flexible supply pipe, a rotary knife driven by said motor, and a sharpening device attached to said motor, said sharpening device having a hand-hold in convenient proximity to the handle of the machine, as and for the purpose described. i

4. In a cloth-cutting machine, the combination of a bed-plate, a vertical standard, an airoylinder adjustably secured to said standard and provided with piston-wheels, a rotary cutter secured to a shaft j ournaled in said oylinder, and intermediate gearing supported by said cylinder, as and for the purpose described.

5. In a cloth-cutting machine, the combination, with a bed-plate and a vertical standard,

' of a rotary motor adj ustably secured to the latter, a flexible supply-pipe, and a rotary knife driven by said motor, as and for the purpose described.

6. In a clotheutting machine, the combination, with a bed-plate and a vertical standard, of a rotary motor secured to the latter, ailexible supply-pipe, and a rotary knife driven by said motor and adj ustably secured to said standard, as and for the purpose described.

7. In a cloth-cutting machine, the combina` tion, with a bedplate and a vertical standard, of a rotary motor adjustably secured to the standard, and a rotary knife driven by said motor and ad j ustabl y secured to sai d standard, as and for the purpose described.
